' To all whom itmwy concern:

Be it known thatl, YANCEY Q. GALnwEL'L,

a citizen of the United q States, residing at Paris,- in the county of Henry vand State of Tennessee, have invented new and useful Im- 11 provements in Padlocks, of which the following is a specification. z I p This, lnvention relates to looks having means directly operative by a separate -e le. ment or key to actuate a slidingbolt or shackle with respect to a stapleor other analogous coeperating device and wherein the use of1;e silient and delicate members is completely avoided. I

The improved features are preferably embodied: in the form of a padl0ck,,but maybe utilizedin a trunk, mortise, or other lock. I The number of necessary parts is reduced to,

a minimum, and consequently the general structure is rendered strong and durable. It is almost. impossibletoick the, improved lock, owing to the particular construction thereof, and the required operation of'the means for actuating the boltor shackle by a,

e. ne of the mostadvantageous featuresor the lock isthe facilitywithwhich the several parts may be assembledor disaSSOciated. x

p The lock-casing composed of body 1 and a closing-plate 2 of similar. contour, which suitable means. The upper central portions of the body 1, and, plate 2 are formed with co inciding recesses 3 and {l to receive a staple or analogous device, and to theleft of the recess-3 of the body and normally covered by the plate 2 is a seat or slot 5 to receive the of thebolt or shackle,' whichwill be I breakage is removably-secured to the body by any.

' ,curv'ed cavity 6, which opens into the recess 3 opposite the seat of slot 5. i The cavity 6 is enlarged toward its. inner extremity and gradually reduced toward its outlet to therecess 3. The closing-plate 2 has an escutch-' seen 7 secured over a suitable key-opening and located at the center near the lower edge. The movable elements of the lock consist mainly'of a bolt or s'hackleactuator or con- .65

troller 8, a bolt or shackle 9, and a pinion 10, the latter being operated by-a key 11 to shift the actuator or controller 8 in opposite direc% .tions in the cavity 6 to expel or retract'the I bolt or shackle 9. One end of the actuator or 76 controller 8 is formed with-a rounded coupling-head 12, havinge tra sversely-reduced neck 13, formed by curved seats Hand 15. Theshackle 9, which is projectableand re tractable through the upper outletof thec'av ity 6 to engage with and be withdrawn from,

' thefseat or slot5, has an inner enlarged coup' ling-extremity 16, with aslot 17 therein open- ,ing-thr'ough the inner end'toreceive the head 12 al d il' G the said formed with guards18with respect to the slot 17 to engagejthe reentrant curved seats 14 I and 15, forming the neck'lb'; The head; 12"

and neck 13'are freely movable in the'slot 17 ,85

to compensate'forvariations in the movement .of the actuator orcontroller 8 and the bolt or I shackle 9', so as to. avoid jamming either ofthe said latter parts. The actuator or controller sandthe'bolt er shackle 9 may be readily ee- 90 '7 'sembled'or'disass ociated through the; medium thecduplilig-hetd .1'2itnd itsneck 13- and"' e meansare' g the slot 17, and no other fastening I required when thesaid parts are assembled to. maintain them in operative relatiomthus're 9 5 duc'ing the. cost ofmanufacture' and facilitate ing' the original assemblage of the parts of the lock, as well as their repair-when found necessary; A further advantageofthismode of connecting the actuator or controller bolt or shackle 9 is that either ofsaid parts may be replaced by a new one in the event of without impairing the entire lock structure. The ends'of the guards18 are'also' rounded, so as tomov'e easily in the seats 14 1 05 and 15 and obviate any restriction in the ready'or easy movementof the actuator or" controller and the bolt or shackle. If the bolt orsha'cklebecomes, broken; or worn to such an extent that it must be replaced by a' 11o new-similar part, it is only necessary to remove the pletez andelevate the'said bolt er- 13 01? the actuator or controller, inner enlarged extremity being- 1 v 8 and mo shackle out of the cavity 6 and substitute the new one therefor-without disconnecting the actuator or controller 8 and then close the look by resetting the plate 2.

The actuator or controller 8, in addition to the head 12 and neck 13 just explained, has a lower elongated curved edge 19, which is held clear of the corresponding curved edge of the cavity 6, and extending longitudinally of the lower portion of the said actuator or controller 8 is a curved slot 20, having its upper shorter wall regularly toothed, as at 21, the lower longer wall being smooth, and projecting through the said slot is a pinion 10, which engages the said upper toothed wall 21 and is insertible into the slot through an enlarged o ening 23 at the right end of said slot. T e pinion 10 is rotatably held on a post 24, projecting outwardly through the cavity 6 from the rear of the body 1, and the outer end of the pinion has an angular spindle 25 projecting therefrom and provided with a lug 26. The key 11 has a bore 27 in its one end to fit over the spindle 25 and a slot 28 to engage the lug 26, and when said key is properly applied the pinion 10 may be rotated, in reverse directions to accordingly move or shift the actuator or controller 8.

rear of the The teeth of the upperwall of the slot 20 are continued through the left terminal or end of said slot, as at 28, to always have the pinion V in engaging position with respect to the'actuator or controller, the curvature of the upper toothed wall 21 of the controller being such as to always maintain the teeth of said wall in positive engagement with the teeth of the pinion 10. Above the slot 20 and in the center of the actuator 01' controller 8 is a shorter curved slot 29, having its upper wall formed as a cam projection 30, the said projection slidably en aging a pin 31, secured to the body and projecting into the slot 29. This slot with its cam projection and the pin 31 operate to hold the actuator or controller 8 in such position as to always insure operative engagement of the pinion 10 with the upper toothed wall 21 of'the slot 20. At the inner terminal of the slot 29 is an upwardly-projecting locking-seat 32 to receive the pin 31 when the actuator or controller is shifted to expel the shackle or bolt into looking position. The function of this seat 32 is to resist movement of the actuator or controller through the exposed portion of the bolt or shackle and the actuation of the pin ion without the aid of the key. In other words, this seat 32 and pin when in engagement one with the other form a lock which prevents movement of the shackle by irregular methods when said shackle is in looking position. The slot 29 at its opposite extremity is slightly deflected upwardly to receive the pin 31 and to hold the actuator in such position that the upper toothed wall 21 will always practically engage the teeth of the pinion 10 without binding on the latter and resist accidental disengagement of the said toothed wall and pinion when the actuator and shackle or bolt are retracted and which disengagement might otherwise ensue if the lock Were subjected to a sudden jar by falling, particularly after the parts had become slightly worn. The end of the slot 29 opposite that having the seat 32 therein also serves as a stop means for the movement of the actuator and to indicate to the operator when the actuator and shackle or bolt are fully retracted to avoid disengagement of the teeth at the right-end extremity of the wall 21 from the pinion.

From the foregoing the operation of the lock will be readily understood, and in various uses it is intended to modify the proportions, dimensions, and minor details with in the scope of the invention.

Having thus fully described the invention, what is claimed is 1.
